Garden Path Edging: Options That Stay Put
Garden path edging is the restraint along each side of a path that stops the surface spreading outwards and stops soil, gravel or lawn creeping in. The best options for a lasting path are a block or brick edging course, natural stone setts or kerbs, all bedded and haunched in concrete. Sleepers, metal and timber edges suit lighter, informal paths.
Whatever it looks like, an edge only works if it is fixed into something solid. Most paths we are asked to repair have failed at the edge first, so this guide covers the choices and, just as importantly, how each one should be installed.
What an edge actually does
Every paving surface pushes outwards under foot traffic. Block paving relies on interlock between units, and that interlock only holds if the outer row cannot move. Gravel wants to spread into the lawn. Slabs at the side of a path are only supported on one side unless something holds them.
An edge restraint takes that sideways load. Without it the outer row tips, the joints open, the surface sinks at the sides and weeds move in. With it, the path keeps its shape for years.
The main edging options
Block or brick edging course: the most versatile. A row of paving blocks or bricks laid on a concrete bed and haunched on the outside face. It can be a matching colour for a clean look or a contrasting soldier course to frame the path.
Natural stone setts and kerbs: heavier and more traditional, well suited to period homes and to sandstone or granite paths. Laid and haunched the same way as blocks.
Sleepers: good for informal gravel paths and for paths that step down a gentle slope. They need firm fixing with posts or pins, and softwood will eventually rot in contact with soil.
Metal edging: steel or aluminium strips give a crisp, almost invisible line between path and lawn or border. Best for gravel and bark paths where the load is light.
Timber boards: the cheapest option and the shortest lived. Fine for a temporary route across a vegetable plot, not for a main path to the door.
Haunching: the part that makes it last
A haunch is a sloped fillet of concrete placed against the outer face of the edging, from the bed up to roughly two thirds of the edging height. It locks the edge in place and transfers load down into the ground. It is the same detail we use on block paving, patios and driveways, and it is the single most common thing missing when an edge fails.
The concrete needs to harden before the path is used, and the haunch should sit low enough that soil or turf can be dressed over it so it is hidden in the finished job.
Matching edging to the path surface
Block paved and slab paths need a rigid edge, so blocks, bricks or stone kerbs on concrete. Resin bound paths need a firm, fixed edge to trowel against, and the edge sets the finished level. Gravel paths suit metal or sleeper edges with a membrane beneath. Against a lawn, set the edge slightly below the turf so the mower can run over it; this doubles as a mowing strip.
If your path already turns muddy or loses its shape, the edge is usually the first thing we check, along with drainage and the base underneath.
Having it done
Edging is normally installed as part of a new path, patio or driveway, and it can also be rebuilt on an existing path where the surface is sound but the sides have gone. We quote on a free site visit, and our ten year guarantee applies to all our work.
Path losing its shape?
We will check the edge, the base and the drainage and quote a proper fix.
Frequently asked questions
What is the best edging for a garden path?
For a path that takes regular use, a block, brick or stone edging course bedded and haunched in concrete lasts longest. Metal and sleeper edges suit lighter gravel or informal paths.
Does path edging need concrete?
Rigid edges such as blocks, bricks and kerbs should be bedded on concrete and haunched on the outside face. Without that the edge moves and the path spreads.
Why is my path spreading at the sides?
Usually because the edge restraint is missing, was never haunched, or the haunching has cracked away. Rebuilding the edge properly stops the spread.
Can edging be added to an existing path?
Often, yes. Where the path surface is still sound, the sides can be cut back and a proper haunched edge built along them.
Is edging work guaranteed?
Yes. Our ten year guarantee applies to all our work, including edging installed with a new or repaired path.
